I bought it while i was in USA it was refubishedEverything was fine while i was in USA.In russia macbook started to freeze while first boot (while it cold) and in idle (only in mac os x 10.8.2, i think it's becouse macbook cools down, in windows efi don't give acces to intel hd 3000, so macbook stays hot: cpu 60C\140F )I changed ram,hdd nothing helped. Ran Apple Service Diagnostic nothing wrong (except for hdd test: error -33000 [wrong drive type] but i think it's becouse of ssd (i changed hdd to ssd to test if hdd is ok)).Reinstalled Mac OS X same, installed windows same.Everything fine in startup manager, or while installing mac os x, or while downloading mac os x (cmd+r in start up manager) and laptop is cold.In games, programs, test everything fine. I think that problem in microcrack (hair crack not sure how in english). Any ideas? Ask any question.

Yes, i tried to unplug all usb things while boot and while idle. One more thing mac os x can freeze even if you just surfing (but if you open one tab with flash it won't). Also i tried to boot from external hdd, the same, if laptop cool it'll freeze.And about freeze, sound loops and i can't do nothing, just reboot, same in windows and mac os x. Only thing that working fine while macbook cool is startup manager.

So did you get it serviced? After a few years your average laptop needs to be opened up to clean the heatsinks and replace the heatsink compound. This sort of work is very common and your average laptop owner thinks that laptops don't need maintenance.Bob
